英文摘要 In order to prolong the lifetime of wireless sensor networks, the paper did some exploring researches on the energyaware route protocol of the wireless sensor networks, a new energysave route protocol was brought forth and implemented. The characters and constraints of the wireless sensor network ware studied firstly, and the methods of the energyaware and energysave route protocols in wireless sensor networks were researched carefully. The energybased radius selfadaptive routing protocol was designed and implemented. The simulation of the protocol was done in the OPNET modeler environment. The performance of energy saving critic, such as end to end delay, data dropped and throughput was compared with sensor protocols for information via negotiation and directed diffusion in similar simulation scene. The results show that switches its running mode with the energy consuming of nodes, so that meet the goal of energy saving of the nodes in wireless sensor networks.
